ZConfig is a general use Python configuration library. It supports a
hierarchical schema-driven configuration model that allows a schema to
specify data conversion routines written in Python. ZConfig's model is
very different from the model support by the ConfigParser module
found in Python's standard library, and is more suitable to
configuration-intensive applications.

- stop using easy_install for installing
- convert to autogenerated packing list
- bump PORTREVISION because the resulting packages changed
- add staging support as side effect of PYDISTUTILS_AUTOPLIST
- move DIST_SUBDIR to more appropriate Makefile "section", and
add it where it is missing

- Make Python 2.5.1 the default Python version
- Add significantly better support in bsd.python.mk for working with
